Along with popularizing of private car, the problem of fuel automobile exhaust emissions environmental pollution is day by day outstanding. Successively put into effect the measure of several restricting vehicle exhaust emissions amount in the world, but these ways can not fundamentally solve tail gas problem of environmental pollution. So along with the development of science and technology, people have been transferred back to electromobile sight again from fuel automobile.
Current electromobile has two kinds of charging modes, contact and noncontact formula. The charging of charging pile contact and the wireless charging parking stall mode that is embedded in underground is mostly adopted to be powered by electromobile on the market, but just at present, above-mentioned power supply device not only needs sizable economic input in universal, and engineering amount is also very huge.

Due to two kinds of wireless power transmission modes based on principle slightly different, therefore both receptions, launch end composition structure also slightly different, but identical, electric energy transmission efficiency is all had great impact by distance, the level angle receive, launched between end. In general, the more near efficiency of distance is more high; Receiving end is more tending towards parallel with launching between end, and electric energy transmission efficiency is more high. But owing to induction charging modes is very harsh for the requirement of coupled transfer distance, and best transmission is apart from maximum only several centimetres, should use very inconvenient; Also can keep higher energy transmission efficiency in the scope that the energy transmission range of electromagentic resonance formula charging modes is a meter nearly, compare way of electromagnetic induction in wireless charging field flexibly convenient, therefore there is considerable application prospect.
